The continued colder than normal temperatures along with frequent Arctic intrusions is causing area rivers to ice up and produce ice jams that in turn back up the flow of water and produce flooding.

The Gallatin river at Logan is one example and now the Beaverhead river at Twin Bridges is another.

Anyone living in these areas need to monitor river levels closely. We encourage you to also take pictures and video and send them to us via email anytime to: newstips@kxlf.com or z7tips@kbzk.com or photo@kbzk.com or photo@kxlf.com.
Here is an official statement on the flooding for both rivers as of 10am Tuesday Jan. 4th, 2011:
